Introducing Avaya Equinox Streaming and Recording
• Transcoding H.323 audio and Video: The CP connects H.323 calls to the Scopia Elite MCUs
(Multipoint Control Units) and/or Equinox Media Servers. When it establishes a video
connection, the CP sends the audio and video data from the MCU/Media Server to the internal
transcoder. The transcoder converts the data into a format that is suitable for streaming.
• Transcoding with H.239: H.239 is an ITU recommendation that allows for establishment of
multiple channels within a single H.323 session. Existing videoconference equipment can be
used to stream audio and video and a secondary channel can stream a slide presentation or
another data stream to the viewers of a program. This function is typically used to stream slide
presentations synchronized with live audio and video. If a program uses a secondary H.239
channel, the encoder inputs the second stream, decodes, scales and mixes it with the main
video input for transcoding/streaming. The streams are then sent to the DN for delivery to the
distribution network. The dual stream can also be recorded as a single MP4 program.
• High definition support: The CP supports high definition video and higher rate streaming quality
and bandwidth. The CP supports the following ITU recommendations:
- H.261 up to CIF Video
- H.262 up to CIF video
- H.263 up to CIF video
- H.264 up to 1080p video
- H.263+ up to 1024 x 768 H.239 data
- H.264 up to 1080p H.239 data
- G.711 audio
- AAC-LC audio
The CP negotiates up to H.264 Level 3.2 video at 1.92 Mbps, and accepts up to 1080p and
down to H.261 QCIF along with G.711 or AAC-LC audio. The streaming resolution and
bandwidth rate depend on what you select for the bitrate when creating the program and what
the Scopia Elite MCU and/or Equinox Media Server negotiates.
Equinox Streaming and Recording Delivery Node
The DN provides on-demand and broadcast video delivery. Used alone or in a hierarchy of devices,
the DN supports thousands of concurrent streams. The DN uses intelligent routing, content caching,
and inherent redundancy to ensure transparent delivery of high-quality video.
Delivery nodes (DN) store all content that is created by the conference point and deliver the content
to client systems at playback time. You must associate the conference point with the delivery nodes.
A source DN is the original DN that receives a recording file from its associated conference point. A
source DN sends the recording file to all of the other DNs in the network.
The Delivery Node Details dialog displays a list of recording files, known as Source Programs and
Distributed Programs. Source programs are programs (recording files) for which this delivery node
is the main source for storage. Distributed programs are programs which other delivery nodes have
forwarded to this delivery node.
Equinox Streaming and Recording Virtual Delivery Node
A virtual delivery node (VDN) delivers content to a global content delivery network (CDN) provider
for cloud-based viewer playback. The appliance and the network of the CDN act as one delivery
mechanism. Therefore, the VDN appliance and the CDN together create the Equinox Streaming and
Recording VDN solution.
